A lot of people miss the 7.3L Ford diesel engines. Many of these engines with 7.3 Liters have over 300,000 miles on them. even though they are not trouble free they are very reliable engines. Most 6.0â€™s have been a nightmare.
It was 25 years ago that Ford introduced the 6.9L Indirect Injection (IDI) engine. That engine’s output was 170 Horsepower and 315 foot-pounds of torque. A new idea on the market was taking shape. Diesel engines in light duty trucks. This was Fords first attempt at using diesel power in any smaller vehicles.
The next model Ford offered was the 7.3L IDI. The engine was produced from 1988-1993. Another reliable engine that took anything thrown at it.
A big time change in the power produced by the 7.3L engine occurred in 1994. The 7.3L was converted to a Direct Injection (DI) engine, a turbocharger was added and the Power Stroke name was introduced. The 7.3L engine was in production until early 2003 and this engine’s performance and durability is what made the Power Stroke name legendary.
Some of the engine features were a waste gated turbocharger, HUEI (hydraulic electric unit injectors) and an air to air inter-cooler. Reliability was the 7.3L’s middle name. This engine is full of power and very reliable when you consider what some people put them through. Take care of the regular maintenance and many of these engines see over 300,000 miles of usage without major repair problems.
In March of 2003 the 6.0L was introduced and the reliable 7.3L was discontinued.
The 6.0L saw a significant increase in horsepower and torque (325 HP and 560 ft-lbs Torque) even with a drastic reduction in engine displacement. The 6.0L also introduced Power Stroke customers to the variable geometry turbocharger, exhaust gas recirculation system and generation two fuel injection system.
Since the introduction of the Ford 6 liter diesel there have been a lot of reliability issues. The people who know more than me about diesel engines in particular agree that when you increase the power of an engine substancially, you stand the chance of loosing reliability.
The 6L engine is great engine when it runs properly, the bugs will get worked out, this is what new technology brings. Some people call the 6L engine job security. It may sound funny, but it keeps mechanics busy at repair shops and dealers (at least as long as there are dealers) and parts suppliers, even engine suppliers stay busy too.
GotEngines.com can fit you up with a 7.3 L diesel or a 6.0L diesel engine. The variety of engines offered ranges from used low mileage engines, which applies to 6L engines mostly since there are not so may low mileage used 7.3L engines, due to attrition.
